PULL TIGHT MOLDING.

Filed Jan. 8, 1929 Patented Junel'Y, 1930 warren stares AUGUST w. scnMIn, F coNNER-svILnE. INDIANA I PULL-TIGHT MOLDING Application filed January 8, 1929. Serial No. 331,121.

This invention relates to an improvement in moldings, trimmings, welts and similar articles, where concealed attaching devices, such as nails or tacks, are employed.

The object of this invention is to devise a construction where the attaching devices can be most readily applied and thereafter be securely and readily concealed. It is manifestly desirable that any folding part of the welt or molding, which is utilized for folding over the attaching device and concealing same, should occupy an initial position such that the attaching device can most readily be applied and yet in a closed or final posip tion should be most readily and securely held in that final position. To that end it is desirable that the parts be, in the closed position and in the initial position, as flexible andinobile as consistent with their final holding action and at the same time it is desirable to eliminate all adhesives that may deteriorate and yet have a locking effect as 351 To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention,

drawings depicting a preferred typical con- 40" struction have been annexed as a part of this disclosure and, in such drawings, like characters of reference denote corresponding parts throughout.

In the drawings Figure 1 is a top plan '45' view showing one portion of the strip in its initial-open position and another portion in its closed position. Fig. 2 is a section of a trimming in open position, while Fig. 3 isa corresponding view showing awire slidingly mounted within the article and Fig.4 is a corresponding view showing the fold in closed position, the wire being shown in dotted lines. Fig. 5 is a sectional view show 151%(1 the attaching means concealed by the In the drawingsthe strip is marked 1 and the folding portion is 2. There are preferably shown stitches 8 secured to theouter edge of the inside surface of the fold 2 and also to the body portion, thesejstitc'hes appearing as two parallelrows with the attaching means 4: positioned intermediate said rows of stitching. There is preferably shown a stiffening substance such as wire 5 which is threaded through the stitches in a wayto enable portions of the wire to slide through said stitches. One end of the wire 5 is anchored to the body of the welt at the point 6 (Fig. 1) and the free end 7 ofthewire projects beyond the end of the welt or. molding to enable the artisan to pull the wire from the serpentine position indicated inFig..3 to the substantially straight position indicated in F ig t. The-wire 5 is preferably a flexible stiffening substance such asthat disclosed in Letters Patent No. 1,387,689 and for that reason the friction and tension will stiffen and hold'open thefolds when the wire is in its normal position as clearly shown in Fig. 3 and will likewise hold thego fold. closed when the wire is drawn or pulled taut into its final position shown'in Fig. 4.

. After the attaching devices 4 have been applied to the welt to secure same to a body of a motor car or any other article the artisan canreadily manipulate the parts so as to pull the member 5 to a positionsuch that the fold 2 Will 'be brought into its final closed position and as indicated in Fig. 1 this may be by a progressive movement, first closingone portion of the welt thereby bringing the member into a substantially straight position as indicated at left side of Fig. 1, which will thereby reduce the friction and strain between the surpentine Wire 5 and the foldable portions which would otherwise hold the folds in open position enabling the other portions of the welt to be closed. It is apparent that after the attaching devices 4: have been concealed throughout the article, then the free end of the Wire can be anchored, thereby locking the fold securely in its closed position.

WVithout further analysis, the foregoing will so fully reveal the gist of this invention that others can, by applying current knowledge, readily adapt it for various utilizations by retaining one or more of the fea tures that, from the standpoint of the prior art, fairly constitute essential characteristics of either the generic or specific aspects of this invention and, therefore such adaptations should be, and are intended to be, comprehended within the meaning and range of equivalency of the following claims.

Having thus revealed this invention, I claim as new and desire to secure the following combinations and elements, or equivalents thereof, by Letters Patent of United States 1. In a welt the combination of a bead portion and a nail concealing portion connected thereto by a nail receiving strip, a flexible stiffening member normally in position for holding said portions separated. means for attaching said member to said portionsand permitting said member to be pulled taut and straightened whereby said concealing portion is folded over on to said strip.

2. As an article of manufacture, a welt comprising a nail concealing portion hingedly connected to a nail receiving strip, a flexible serpentine stiffening member normally holding said portions separated, attaching devices for said member permitting portions thereof to be pulled along said strip into a straightened position whereby said concealing portion will be folded upon said strip. 7 I r 3. In welt the combination of a flat strip comprising a nail receiving portion and a nail concealing portion, said last mentioned portion being capable of being folded over "and on to said first mentioned portion, with a flexible serpentine member'normally Stiffening said concealing portion, means for nected together, a flexible re-enforcing member. normally holding said portions extended into open position, attaching devices for loosely holding portions of said member on said strip, permitting said member to be pulled taut into straightened position for forcing said concealing portion upon said strip.

In witness whereof, I have hereunto sub scribed my name.
